80例下前牙松牙固定术的长期疗效观察

Long Term Observation of Splinted Anterior Mandibular Teeth in 80 Periodontitis Patients

目的:介绍一种针对下前牙的改良松牙固定术,分析常规和改良下前牙松牙固定术的长期疗效。方法:回顾性分析80例行下前牙松牙固定患者的临床资料,记录固定患牙0、3、6、12个月的牙周、邻面龋以及牙周夹板的修理情况。结果:80例下前牙松牙固定患者,54例行常规松牙固定术,26例行改良松牙固定术,平均观察(4.85±3.14)年,患牙牙周状况改善明显,期间3例因反复炎症拔除单颗下前牙后行改良松牙固定术。结论:松牙固定术是解决下前牙松动,长期保存患牙的有效方法。改良松牙固定术为拔除单颗预后无望下前牙后,提供了一种新的修复选择。

Objective:To introduce a modified splint method for lower anterior teeth,and analyze the long-term effect of conventional and modified splints in periodontitis patients.Methods:Eighty patients involving lower anterior teeth splinting were retrospectively accessed.The periodontal and proximal caries conditions of splinted teeth in 0,3,6,and 12 months and the repair of splint were recorded.Results:Eighty patients were followed over(4.85±3.14)(range:1.0-8.5)years.The periodontal condition of the affected teeth improved significantly.During this period,3 patients underwent modified splint after extracting a single lower anterior tooth due to repeated inflammation.Conclusion:Fiber-reinforced composites splint is an effective method to fix the loose lower anterior teeth and preserve the affected teeth for a long time.The modified splint provides a new restoration choice for the extraction of a single lower anterior tooth with poor prognosis.
